Diễn đàn hỗ trợ Firefox

I have the latest version of Firefox. I still keep getting the prompts to download the latest version. When I go to system info, it shows I have the latest version it is asking me to download. When I do a manual search for the latest version, it always says it failed to search for the latest download.

My local network is 10.10.10.x and I can't log into my NAS, web server or another computer on the local network... Internet access is fine. Happens on Wi-Fi or Ethernet.

If I access the same web address using Safari or Chrome it works just fine and it used to work before the software update to the 147 build.

So what switch/setting got kicked over during the upgrade that I have to turn off?

These kind of issues really make me mad at the Firefox Dev team... and I'm a very long time user.

I want youtube to go back to the list of websites on the url drop down menu. I'm annoyed that Heroforge replaced it after only two visits to the website and I don't know why it even did that.

Hi,

I just updated to the latest version of Mozilla FireFox and my bookmarks dissappeard.

All are gone, I wonder how I can get them back?

Many thanks,

When Fox News has a new article and I click on it to read, I now get a 500 Error over a blank page. Is there a way to correct this? It has never happened before and only seems to have appeared in the last update of last week.

I get an error message when trying to load Newsmax.com - It comes up with no problem in Safari - maybe I should use Safari as my default browser.

I on MacOS and I'm facing this issue last half of the year. As usual mac book user, I have many WIP items on my laptop, so I don't reload my laptop every day, even months it can leave without reloading.

So, after a workday I just closing it and come back tomorrow. When I back to the work and want to open new tab: Jira, Gmail, LinkedIn any other tabs - FireFox just keeping in loading state. In comparison, the Google Chrome that opened as well all the time but with fewer tabs, open the same links in seconds.

I though the FireFox is not latest version, and updating or re-starting of it, sometimes helped me to fix the issue. But now it seems stopped work either.

So, after a 5 years on FireFox I'm seriously started about my migration back to Google Chrome. I'm not sure that you can help me in this forum, but at least I would like to hear you option. Maybe anyone else have seen such behavior also and FireFox could find the issue

I have been using 1Password 7 to manage my login credentials. It includes a Firefox extension to fill in account names and passwords in login alerts and pages.

Firefox 147.0.1 (macOS aarch64) in January 2026 has broken 1Password 7's ability to fill in account names and passwords.

To reproduce: 1. Install 1Password 7 Version 7.9.11 (70911000) and its extension version 4.7.5.90 in Firefox 147.0.1 on macOS. 2. Visit a URL for which 1Password 7 has login credentials. 3. Click on the toolbar icon for 1Password 7. A 1Password 7 dialogue box pops down from the icon, containing the username and password for that URL. 4. Click the Autofill button in that dialogue box.

Observed behaviour: 1. Username and Password fields remain blank.

Expected behaviour: 1. Username and Password from 1Password 7 appear in the Username and Password fields.

For approximately the last three months, there was a partial failure similar to this. 1. 1Password 7 popdown dialogue moves from the toolbar icon to the Firefox tab for that URL. 2. Username and Password fields remain blank. 3. Workaround: click in the username field, then tab 2-4 times to further UI objects in the login credentials form. Then click the 1Password toolbar icon, then click the Autofill button in the popdown dialogue. Then, the Username and Password from 1Password 7 appear in the Username and Password fields.

The expected behaviour occurs for the same URLs in Safari.

Thus I suspect that Firefox has somehow changed its behaviour in the last few months to cause this regression. I have not changed the 1Password software versions in this time, because I am intentionally using a previous version of 1Password.

I am looking for a fix or workaround which works with my current 1Password software version. I am not interested in a solution which requires me to upgrade to the current version of 1Password. (The current version of 1Password imposes a feature which I am resisting.) I realise that this reduces the chance that I can persuade the Firefox team to find and correct this regression.

I went into settings and searched passwords. then clicked onto saved passwords and tried removing what I thought was the password for a site. However when I log into the site the password continues to autofill. I'm wondering if I'm not getting to the right spot to deal with autofilling passwords?

I teach an online Adobe Illustrator Course. Students upload (.ai) Adobe Illustrator files. Not .svg or .pdf. But Firefox changes the (.ai) extension to (.pdf) upon downloading. This is HIGHLY irritating. Firefox, in prior versions, did not do this. In Firefox settings for Applications, there isn't a choice for .ai (Adobe Illustrator) files. I 'assume' that when AI (artificial intelligence) became available is when Firefox began automatically changing (.ai) files to (.pdf). PLEASE SOLVE this as I have to manually change the (.pdf) extension BACK to (.ai) HUNDREDS of times a day.

The last automatic browser update (147.0.3 (aarch64)) has wiped off all changes I made to bookmarks and passwords from the past year.

How can I go back to a previous version and recover my details?

This browser version is terrible and looks exactly like Microsoft Edge which is not intuitive at all. I don't want to set up multiple personas, Its just me and the one computer?

Please help me. Kerri

[article] This article claims there is an "AI Controls" section in Settings. This is not found in v 147.03 (up to date) for Mac. Please let me know how to disable all AI in Firefox.
